gemd.entity.attribute.property module

class gemd.entity.attribute.property.Property(name: str, *, template: Optional[Union[AttributeTemplate, LinkByUID]] = None, origin: Union[Origin, str] = Origin.UNKNOWN, value: Optional[BaseValue] = None, notes: Optional[str] = None, file_links: Optional[Union[Iterable[FileLink], FileLink]] = None)

Bases: BaseAttribute

Property of a material, measured in a MeasurementRun or specified in a MaterialSpec.

Properties are characteristics of a material that could be measured, e.g. chemical composition, density, yield strength.

Parameters

  • name (str) – Required name of the attribute. Each attribute within an object must have a unique name.

  • notes (str) – Optional free-form notes about the attribute.

  • value (BaseValue) – The value of the attribute.

  • template (AttributeTemplate) – Attribute template that defines the allowed bounds of this attribute. If a template and value are both present then the value must be within the template bounds.

  • origin (str) – The origin of the attribute. Must be one of “measured”, “predicted”, “summary”, “specified”, “computed”, or “unknown.” Default is “unknown.”

  • file_links (List[FileLink]) – Links to files associated with the attribute.

as_dict() → Dict[str, Any]

Convert the object to a dictionary.

Returns

A dictionary representation of the object, where the keys are its fields.

Return type

dict

static build(d: Mapping[str, Any]) → DictSerializableType

Build an object from a JSON dictionary.

This differs from from_dict in that the values themselves may also be dictionaries corresponding to serialized DictSerializable objects.

Parameters

d (dict) – The object as a serialized dictionary.

Returns

The deserialized object.

Return type

DictSerializable

dump() → Dict[str, Any]

Convert the object to a JSON dictionary, so that every entry is serialized.

Uses the json encoder client, so objects with uids are converted to LinkByUID dictionaries.

Returns

A string representation of the object as a dictionary.

Return type

str

classmethod from_dict(d: Mapping[str, Any]) → DictSerializableType

Reconstitute the object from a dictionary.

Parameters

d (dict) – The object as a dictionary of key-value pairs that correspond to the object’s fields.

Returns

The deserialized object.

Return type

DictSerializable

Get the file links.

property origin: Origin

Get the origin.

skip = {}
property template: Optional[Union[AttributeTemplate, LinkByUID]]

Get the template.

typ = 'property'
property value: BaseValue

Get the value.
